Kool-Pak® Power Film Resistors

The MPM20 Kool-Pak® power film resistors from Caddock are pure tin free design for high performance industrial and military applications in TO-220 style power package with metal mounting tab. The resistance range is from 0.02Ω up to 10kΩ with a power rating of up to 20W at +25°C case temperature. The MPM20 series tolerance is ±1.0% (±0.5% is available for most resistance values). MPM20 series uses Caddock’s proven Micronox® resistance film system to provide a compact heat sink mountable resistor. The non-inductive design makes this resistor ideal in high frequency communications, power switching circuits and snubbers.
